Well I have considered doing the texture map route, but I really want to see if I can get the geometry to work first. I am so close that I feel like it "should" work and I know there are people out there that have been successful at it like Thomas Suurland (but he uses 3D studio). I'm thinking that there's some deformation that needs to happen to get the scaloping to go away.

OK, I give. I cannot figure out how to get that cool polygonal tire tread happening as found on Thomas Suurland's site www.suurland.com. I was trying the VW beetle tutorial and just cannot get it.

If anyone has a good direction for me to follow for doing that I would appreciate it as I would really like to model this tread instead of doing a bump map.

Any ideas?

From what I've seen Brian do, he creates a basic pattern out of blocks of geometry, and then duplicates that around the perimeter of the wheel. Then merge them together.

This is using Polygons. I wouldn't even attempt that with Nurbs. >shiver< Scary. user added image

Yes making little blocks and then duplicating them is a good way for making treads. There is like a mini tut somewhere here in the posts. sorry can't give you the url because in a hurry, but just search for mclaren and then in ereitz's post it should be on one of the pages.

however nurbs can be done by just revolving a lat surface and then applying a bump map to it. I've done both poly and nurbs metods and the work fine.

polys would probably be easier though.

Well I'm not sure how to try the polygonal approach, so maybe I'll give it a try. Here's my latest attempt.

It's a NURBS CV Curve, with a lofted piece in the middle (the angular type piece of tread), then scaled across the Z axis at -1 then I duplicated the entire tread piece about 60 times (cannot remember due to many trial and errors), then used the BEND deformation tool to bend it.

As you can see, there are imperfections using this method and I don't know if they are because my tread "slices" were to wide or what, but a good attempt at tackling the NURBS avenue non-the-less I think.

If there are some good tutorials on how to achieve the perfect tread look with polys or anything else, I'd love to see them. I did search for the McLaren but didn't find anything on making tires. Perhaps I didn't look close enough.

Hi sjurick. The thread where I go over how I made my tire is here:

This is apparantly a technique used by brian ellebracht among others so in other words good user added image

Only problem is it ups your poly count a lot.

hey sjurick

first of all i'd say that your wheel looks pretty good alreayd. if it wans't for the seams i'd say it's finished.

sorry i couldn't give you the adress before but i was at school and was not suposed to use the internet user added image
